The Hover-Cam is a device employed by the Kingdom of Acorn to travel into hostile areas and record valuable information. One such device accompanied Sonic the Hedgehog on a mission to Old Megaopolis to stop Dr. Eggman's nuclear attack on Knothole. As a result, it recorded his injury at the hands of Mecha, much to the horror of Princess Sally. (StH: #132, #133)
